摘要： Embodiments of the invention are directed to collecting, by a computer system, sensor data of a manufacturing system, the sensor data being measured at intervals smaller than a time interval of a target measurement of the manufacturing system. The sensor data is determined to have a relationship to the target measurement. A synthetic target measurement is generated at an interval smaller than the time interval based on the relationship. An advance warning is automatically generated for the target measurement based on the synthetic target measurement within the interval smaller than the time interval.

摘要： A system and method for dispense characterization is disclosed. According to particular embodiments of the dispense characterization system and method, volumes of dispensed liquids can be determined. In more particular embodiments, additional characteristics and combinations of characteristics of a liquid dispensing event can be determined. Examples of additional characteristics that can be determined include the shape of the dispensing event, the velocity of the dispensing event, and the trajectory of the dispensing event. The dispense characterization system and method can be employed in automated biological sample analysis systems, and are particularly suited for monitoring liquid reagent dispensing events that deliver liquid reagents to a surface of a microscope slide holding a biological sample.

摘要： A water management system effective for managing and metering water usage and detecting and reducing water leaks is described herein. The water management system can detect a leak when a volume of water flow or change in water pressure detected by a water meter of the system is uncharacteristic for a given day and time of day at the node. Upon detecting the leak, the system alerts the user, and in some situations, remotely shuts off a water supply to preemptively address a water leakage issue.

摘要： A method for fluid flow measurement for a discrete area of a fluid supply network, where the fluid supply network includes a network of pipes that includes a main pipe for transporting fluid from a source into the fluid supply network for delivery to consumers, wherein the main pipe crosses a boundary between the discrete area and a further area of the fluid supply network, which is outside of the discrete area, and a plurality of distribution pipes each transport fluid from the main pipe to a consumer, where fluid pressure and the fluid consumption on at least two selected key metering points located inside and outside of the discrete area are measured, and where the fluid pressure and the fluid consumption measured on these selected key metering points the fluid flow in the main pipe that crosses the boundary of the discrete area is calculated.

摘要： Techniques for the design and operation of an efficient battery-powered meter are described herein. A metrology unit of the meter may be at least partially located in the gas flow of a pipe, and measures gas flow rate data according to a static flow sensor. The metrology unit calculates raw gas-volume data using at least the flow rate data as input. The metrology unit measures gas temperature to produce gas temperature data, and adjusts the raw gas-volume data, based at least in part on the gas temperature data, to produce corrected gas-volume data. The metrology unit accumulates the corrected gas-volume data over multiple minutes, hours or even days, and then sends the accumulated corrected gas-volume data to an index unit of the meter. By accumulating the data over time, fewer data transmissions are required. The index unit may send the accumulated the accumulated corrected gas-volume data to a utility server.

摘要： A water usage monitor can include a housing having a fluid flow path, a fluid inlet in fluid communication with the fluid flow path, and a fluid outlet in fluid communication with the fluid flow path. The housing can include a dry housing interior fluidly isolated from the fluid flow path. The monitor preferably includes a power generator configured to generate a voltage when fluid flows through the fluid flow path and at least one sensor configured to measure at least one characteristic of a fluid flowing through the fluid flow path. The monitor can include a signal generator configured transmit signals from the power generator and from the at least one sensor to a remote processor. The power generator can be configured to power both the at least one sensor and the signal generator in response to fluid flow through the fluid flow path.
